Which cloud “As a Service” model is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications?

(A) Software as a Service
(B) Platform as a Service
(C) Infrastructure as a Service
(D) Database as a Service

Platform as a Service is the correct answer.

PaaS is primarily used by developers who are building software or applications. A PaaS solution provides the platform for developers to create unique, customizable software. This means developers don’t need to start from scratch when creating applications, saving them a lot of time (and money) on writing extensive code. PaaS is a popular choice for businesses who want to create unique applications without spending a fortune or taking on all the responsibility. PaaS examples: Heroku, Apache Stratos, Magento Commerce Cloud.
